8dpiui hpt negative

So I alway start testing at 8dp, it's better to know early than to have all hopes up then be crushed at once. It's always very hard to watch that dreadful signal line becomes stronger and stronger and that second magical line does not appear. By this time if the strip isn't even picking up a squint worth shadow, I know better luck next time. An I being pessimistic? I think I'm just scared.
